根据大亚基的 D1/D2 结构域和几乎完整的小亚基 rRNA 基因的组合序列，对属于 Debaryomyces、Lodderomyces、Spathaspora 和 Yamadazyma 属的物种，以及也形成辅酶 Q-9 的毕赤酵母属和念珠菌属的选定物种进行系统发育分析。属于德巴利酵母属的物种分为三个分支，属于毕赤酵母属的物种分布在六个分支中。这些得到充分支持的进化枝被解释为属，并根据该分析，提出了以下新属：Babjeviella、Meyerozyma、Millerozyma、Priceomyces 和 Scheffersomyces。恢复并修正了 Schwanniomyces 属，并对 Yamadazyma 属进行了系统发育定义。这项研究提出了 23 个新组合和 3 个新等级。前面的属是一个单一的大进化枝的成员，建议将这个进化枝划定为新的Debaryomycetaceae科。
Species assigned to the genera Debaryomyces, Lodderomyces, Spathaspora, and Yamadazyma, as well as selected species of Pichia and Candida that also form coenzyme Q-9, were phylogenetically analyzed from the combined sequences of the D1/D2 domains of the large subunit and the nearly complete small subunit rRNA genes. Species assigned to Debaryomyces partitioned into three clades and species assigned to Pichia were distributed among six clades. These well-supported clades were interpreted as genera, and from this analysis, the following new genera are proposed: Babjeviella, Meyerozyma, Millerozyma, Priceomyces, and Scheffersomyces. The genus Schwanniomyces was reinstated and emended, and the genus Yamadazyma was phylogenetically defined. From this study, 23 new combinations and 3 new ranks are proposed. The preceding genera are members of a single, large clade, and it is proposed to delineate this clade as the new family Debaryomycetaceae.
